The Lowdown
Alright, grab a coffee and listen up, this is a weird one. We're looking at the Kohala Lighthouse (Big Island) reef break, and to be honest, for the first week and a half, it's a write-off. The wind is a nightmare. We've got a solid, consistent swell coming in from the ENE, but it's absolutely hammered by a fresh cross-shore breeze that just won't let up. Friday the 24th through to Tuesday the 29th, the surf is there, with heights between 6ft and 8ft, but the conditions are just plain ugly—lumpy cross-chop making it a total mess. The wave energy is moderate to strong (328 to 2260), but it's wasted. You wouldn't paddle out for this.
Then, on Wednesday morning the 29th, the whole game changes. The wind swings to the WSW at a mere 6 mph and it goes completely glassy. The swell drops to a clean 6ft from the NE, with moderate energy (599). The report says "expect very good surf conditions". This is our one true standout. The water is a warm 80°, which is about average for this time of year, so no surprises there. But that glassy morning? That's the window. It's a reef break, so it handles that NE groundswell beautifully, and it's a consistent spot, though you might run into a few others with the same idea. Get it while it's good, because by the afternoon the wind turns back onshore.
After that, it's back to the same old story: strong cross-shore winds and lumpy surf from the 30th all the way through August 6th. The swell hangs around, but the quality is poor. The only other glimmer is on the morning of Friday, August 7th, which is nine days out. We get another glassy window, this time with a light W wind. The swell is a bit smaller at 4ft from the NE, but super clean. It's a long-range call, so less certain, but it's worth keeping an eye on.
For the rest of the run, from August 8th onward, the wind is back, and the energy drops off. It's a case of a long, blank run with a couple of tiny, perfect windows. Don't waste your time on the messy stuff. Wait for that glass.

Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Kohala Lighthouse may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself.
